A	0.12
B	0.24
C	0.36
D	0.48

Explanation:

Detailed explanation-1: -So, the correct answer is ‘0.64’

Detailed explanation-2: -if the allele frequencies in a population with two alleles at a locus are p and q, then the expected genotype frequencies are p2, 2pq, and q2. This frequency distribution will not change from generation to generation once a population is in Hardy-Weinberg equilibrium.

Detailed explanation-3: -In a population that is in Hardy Weinberg equilibrium, the frequency of a recessive allele for a certain hereditary trait is 0.20.

Detailed explanation-4: -In a population that is in Hardy-Weinberg equilibrium, the frequency of homozygous dominant individuals is 0.36.
